To oZZ whom it may concern:

it known that we, EDWIN M. VVHEE LUCK, residing at llfilinneapolis, in the county of Hennepin, EMERY F. -Wlntmnoox, residing at Northtield, in the county of Rice, and DicnncsoN O. ll nentocn, residing at Mid nenpolis, in the county of -Hennepin, State of illinnesote, all citizens of the United .ttntes, have jointly invented certain new' and useful Improvements in GuidingDevices for lllow-E'iotors, oi'which the following; is at f-ipi.(jifl(f.ll'tl()ll.-

Uur invention relates to trsction'cngines or motors used in plowing; and its object is to provlde means for guiding themotor toeouse it to travel at a proper distance from and along the side of a previously formed furrow. This object, we accomplish by means of :1 shoe or similar device supported a. suitable distance in front ofthe' motor and adopted to contact with the unplowed side of oflurrow and thereby guide the motor.

Our improven'ient' is illustrated. in the accompanying drawings, in which- 1* l is ztplonview and Fig. 2e side on. of on engine or motor embodying our *ovem nt, showing the guide-shoe 1n opon pt t1on. 1n 2. furrow and engaging he lend-side thereof; Fig. is it view sinnior to 2-, but sl'iowiny, the

guirfieshoe raised above the surface of the,

. operator, 3 the explosive engine, 4 the driverr, the'reor wheels, (5 the front "Z the divided front axle, which is ably suspended from the frame 1 by 8 and, stayed by braces l); '10 the anl. pivotedto the nude '2', and ll the the pivoted members of the To the arms it) are fastened the the plowed ground.

t n noble choin 12 which runs srlnintl at pulley E3 on the end of an opereting rod 14 which is journa-Ied in a hanger 15 and extends rearward and has :1 hand wheel 16 in convenient position for an operator on the platform 2 to turn it for steering the motor. A gang of plows (not shown) may be connected to the motor frame the customary way by the chains. 17 or rods, or other suitable means, to enable the motor to draw the gang for plowing. All of these parts may he of any usual or suitable construction.

To guide the motor and plows in proper direction with relation to the previously plowed ground, end to. relieve the operator of the strain and labor of giving constant attention to the steering devices while plow- .ing, We provide a guide-shoe 18 arranged a short distance in front of the motor and adopted to bear against the lend-side of a furrow.

The shoe may be of any suitable shape and construction. As shown in the drewin it consists of it flat base19 having its ront portion 20 upwardly cnrved,ond an upright side 21'. rising; from the hose and having its front portion 22 rounded or beveled. The base 19 is adapted to slide on the furrow bottom 23, While the side 21 is adapted to con tact with land-side 2 of the furrow to prevent the motor from moving away from the furrow; and the operator con, by settlng the steeringngeor ilfposition to give the m0- tor o. slight tendency to move in that direc- .tion,yohviote any tendency of the motor to move inthe opposite direction, or toward Such guide-shoe is not only on no to the operator in steering the machine, hot-in effect is made to servess o. positive and pi'scticnily m'itornotic guide for the machine during the plowing along the.

side of :1 previously formed furrow.

it is preferable to provide the shoe with c. relatively wide trend, as shown; but; if Cie sired, the hose 19, or trend, may he dis pensed with, in which case, under some nonditions, it would be desirable to hold-tho shoein' suspension to prevent it from cutting .too deeply into the furrow bottom.-

.the shoe may be suspended by a, limped arm. 25 from the front end of o corrierbsr 26, the rear end of which. is journnlcd on o projecting portion 27 of the spindle of one of the steering wheels t3. The bar is stayed by o. hroee 2t) pivotzilly connected to the axle-arm 10 between the wheel and frame; I and it may be also yieldingly stayed by a coil-spring 29 connecting it with the axle 7 For raising and lowering the shoe its carrier 26 is supported on a curved support 30, which preferably consists of apiece of gaspipe. To enable thecarrier 26 to adjust itself along its support as required when the direction of travel of the'steering wheels is changed, anti-friction rollers 31 supported from the carrier bar by a pair of hangers 32 engage the upper and lower surfaces of the support 30 and allow the carrier to move freely thereon in lateral direction between the stops 33 and 34 provided on the support to prevent movement beyond-proper limits.

To enable the support 30 to be operated for raising and lowering the guide shoe it is connected by aneye35'on its inner end with an eye-bolt 36 secured to the front of the fixed axle 7; and a cable 37 fastened to the support near. its middle is made to run on a pulley 38 mounted on a standard 39 at the front of the frame 1 and extends to a drum 40 on a transverse shaft 41 j ournaled on the under side of the main frame. A sprocket- 'wheel 42, on the shaft 41 is connected by a chain 43 with a sprocket-wheel t loose on: the shaft 45 of the motor driving mechanism but. provided with afr'iction disk 46 .on its side adapted to'be engaged by a friction clutch member 47 splined 011 the shaft .45; and a clutch-shifter 48, pivoted at 4%) to a cross-bar 50, enables theroperator at; will ;to start and stop the'cablc winding mechanism to raise and lower the guideshoe device s. To hold the latter. in'their adiu'stedpositions a; ratchet 51 provided on the. shaft 41 is engaged by a dog 52 pivoted at .53 to the frame 'ing engagement with the ratchet.

Having described our invention, what we claim and desire to secure by Letters Pat ent is 1. The combination with a plow motor, of a guide-shoe arranged in advance thereof in a furrow and having its working side beveled or rounded at the front and adapted to bear against the land-side of the furrow, a'

carrier therefor pivotally connected to the axle of a steering wheel, a vertically 1novable support on which the carrier may move will gravitate to the freely in lateral direction, and means for raising and lowering such support and with it the carrier andshoe, substantially as set forth;

2. The combination with a low motor, of a guide-shoe arranged in 'atvance' thereof in .a furrow and vhaving its working side beveled or rounded at the front and adapted a guide-shoearranged in advancethereofin a furrow and having itsworking side beveled .or rounded at. the front and adapted to bearagains't the land-side of the furrow,

a carrier thereforpivotal'ly connected to the axle of a steering 'wheel, a vertically movable support on which the carrier may move,

freely in lateral direction, and a spring for yieldin ly holding the shoe to contact with the lan ;s'ide of thefurrow, substantially as set foi't-h.
